believed corners, characterised in comprising a reading register arranged
at the base of the matrix. The register is bent to follow the bevelled
corners of the chip and thus comprises a horizontal piece and two oblique
pieces. The sensor further comprises means (ZI.sub.n) to direct the
photosensitive charges form the columns terminating opposite the beveled
